Satellites achieve tangential velocity primarily through a two-phase launch process. Initially, they are launched vertically to penetrate the lower atmosphere, followed by a horizontal acceleration to reach the required speed for orbit. This horizontal motion is crucial for maintaining a stable orbit around the Earth. Understanding this process is essential for comprehending how satellites remain in space for extended periods. The mechanics of this launch strategy highlight the complexities of orbital dynamics.

I guess the short answer is "that's rocket science"!
Basically the satellite is launched vertically to get through the lower part of the atmosphere, but then accelerates horizontally to achieve the necessary tangential velocity.
There's a good explanation here, for example:

Power = Force v Speed
Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W
Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same?
I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
